Maintenance

What this chapter contains

This chapter contains preventive maintenance instructions.

Safety instructions

Only a qualified electrician is allowed to perform the maintenance.
Before starting work inside the cabinet,
• isolate the drive from the supply (note that any switch-disconnector installed in
the drive does not switch off the voltage from the input terminals)
• wait for 5 minutes to let the intermediate circuit capacitors discharge
• open the cabinet doors
• ensure there is no dangerous voltage present by measuring the voltage of the
input terminals and the intermediate circuit terminals.

Maintenance intervals

If installed in an appropriate environment, the drive requires very little maintenance.
This table lists the routine maintenance intervals recommended by ABB.
